Grid Column, Remove padding

Hello,

This is my first post on the forum. I'm testing your framework and the Grid component.

I have an issue using it. My request seems really easy but I cannot find the solution.

How to shrink all columns to perfectly fit the content? Right now there is a left and right padding which I think is due to "center option"?. If I try to reduce the width of the columns my text get cut off. 

Thank yo for your help!
